The correct number is 550 rock songs.

Step-by-step explanation:

To find this, we start by determining how many songs there were in each trial.

5+4+3+2+6 = 20

3+3+5+4+5 = 20

Next we need to find the average number of rock songs in the trials.

(6+5)/2 = 5.5

Now to find the average percentage of songs, divide the rock songs by overall.

5.5/20 = 27.5%

Now we can multiply that percentage by the total number of songs on the mp3 player.

2000*27.5% = 550 Songs

based on context clues you gave i'm assuming the answer would be c.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
